Phosphine 2,2-dimethylhydrazino diphenyl

Boiling a solution of (2,2-dimethylhydrazino)diphenyl-phosphine in benzene overnight in contact with dry air causes precipitation of the oxide, (C8H5)2P(0)NHN(CH3)2 (m.p. 167 to 168°). Addition of a stoichiometric amount of sulfur to a boiling benzene solution of (2,2-dimethylhydrazino) diphenylphosphine yields, on cooling, the sulfide, (C H5)2P(S)NHN(CH3)2 (m.p. 95.5 to 97.0°). Alkylation to [(C6H5)2(CH3)PNHN(CH3)2]I (m.p. 156 to 158°) occurs upon reaction with methyl iodide in ether. Reaction with chloramine in ether yields the aminophosphonivun salt, [(C,H,)2P(NH2)NHN(CH,)2]C1 (m.p. 195°). All of the above-described derivatives are colorless solids.
